In Figs. 1, 2, and 3 there is shown a fixture for controlling the flow of water to two outlets. such as a tub spout and an overhead shower nozzle, associated with a bath tub. This fixture has fittings l. and 2 adapted to 9U be attached to hot and cold water pipes and these fittings have forwardly extending valve casings 3 and 4 in which are mounted suitable valves for controlling the delivery of the hot and cold water. The casings 3 and 4 extend "'i at their forward ends through the wall of the bath room and stems 5 and 6 of the hot and cold water valves project beyond the forward ends of the casings and carry suitable handles i' and 8 which may be operated to open or close the valves. The fittings 1 and 2 have inwardly extending nipples 9 and 10 to whichthe opposite ends of the diverter fitting 11 are connected. The fitting 11 has a passageway,7 12 which extends the fullV length thereof through which hot water may pass from one end and cold water from the other. The fitting 11 has an enlarged central portion 13, in the interior of which there is formed a chamberv 14, the walls of which are formed integrally with the fitting, the chamber 14 extending from the front side ofthe fitting toward the rear side thereof and from the top to the bottom of the fitting, the passager12`extending past the rear end of the chamber. A nozzle 15 is secured in a threaded opening in the rear end of the chamber 14 and extends forwardly to a point adjacent the forward' end of the chamber, the front wall of the chamber having an opening'l of slightly larger diameter than the nozzle 15 through which the nozzle may be inserted when it is secured in place to the rear wall of the chamber. The nozzle 15 is in alignment with the opening 16 and has a restricted opening 17 at its forward end through which the stream of water is directed centrally through the opening 16. l A tubular valve casing 18 is formed integrally with the fitting 11 and extends forwardly from the chamber 14. the opening 16 being positioned centrally of the casing 18. A valve seat 19 is formed around the opening 16 on the outer side of the chamber wall and a valve 2O formed to fit upon the seat 19 is mounted in the casing 18 for the movement toward or from the seat. The valve 2O has a stem 21 extending forwardly through thel outer end of the casing 18 and this stem is provided with a handle 22 midway between the handles '7 and 8 of the hot and cold watervalves by means of which the valve stem may beturned to advance or retract the valve. Projecting downwardly from the under side of the casing 18 immediately in front of the opening 16 there is a nipple 23 to which is attached a short vertical pipe 24 which is connected byr means of an elbow 25 to the tub spout 26. n

The nozzle 15 extends from the rear wall of the chamber 14 to adjacent the front wall of the chamber, there being a narrow openn ing y27 between theend of the nozzle 15 and the wall of the chamber through which communication is established between the pas sageway through the nozzle 15 and opening 16 and a space 28 in the chamber 14 surrounding the nozzle 15. At the top of the fitting 11 there is an upwardly extending nipple 29 adapted to receive a pipe 30, the

nipple 29 opening into the space 28 surrounding the nozzle 15.

Assuming the valve 20 is in open position, the hot and cold water coming from the opposite ends of the Ytting 11 enters the rear end of the nozzle 15 and is directed through the opening 16 into the valve casing 18 and passes downwardly through. the pipe 24 to the tub spout 26. The nozzle 15 serves to direct the stream of water through the opening 16 and to create a suction through the restricted opening 227 so that all of the water is carried into the chamber 18 and through the spout 26. If the valve 20 be closed, the water passing through the nozzle 15 will be forced laterally through the restricted opening 2? yinto the space 28 surrounding the nozzle and through the nipple 29 to the pipe 30 leading to the overhead nozzle or other discharge outlet.

Figs. 4 and 5 are a modification of the invention in which all. of the valves are placed at the levelof the tub spout. In. this modifi cation, the construction of the diverter fitting is the same as in the modification above described, except that the valve is not mounted directly in the forwardly extending portion of the diverter casing, which, in this instance, forms the discharge conduit. The diverter fitting 31 shown in 4 and 5 has a forwardly extending tubular portion 32 formed integrally therewith midway between the ends thereof. and this extension forms a continuation of the chamber 14 into which the nozzle 15 projects. To the forward end of the tubular extension 32 there is attached a discharge spout 83 which is provided with a closure valve 34 by means of which the flow of water through the spout may be cut off.

When the valve 34 is open, the water is forced by the nozzle 15 through the spout 33. When the valve 34 is closed back pressure is developed which forces the water into the space 28 surrounding the nozzle 15 and out through the discharge conduit 30.

Figs. 6, 7, and 8 of the drawings show a ,modified form of diverter fitting for use with a valve controlled discharge spout where the spout is positioned at a level below that of the fitting. In this case, fitting 36 is provided with a short forwardly projecting extension 37 into which the nozzle 15 delivers, the extension 37 having on the under side thereof a nipple 38 adapted to receive a vertical pipe 39 which is connected at its lower end to a dischargespout 40 which is provided with a valve 41 by means of which it may be opened and closed. As in the modification previously described, the nozzle 15 serves to maintain the flow through the discharge spout when the valve is open and when the valve is closed the resulting back pressure forces the water yup through the discharge pipe 30. It has been found desirable, however, in this modi-V e back pressure in the chamber.

fication to provide a deiiector or balile member 42 in the extension 37 a short distance ahead of the nozzle 15in order to deflect the stream downwardly immediately adjacent the nozzle and prevent creation of back pressure in the elbow formed by the extension 37.

In Figs. 9 to 12, the invention is shown applied to a kitchen sink cock which is provided with threaded nipples 43 at the opposite ends thereof adapted to be connected to hot and cold water pipes, the nipples 43 being provided with nuts 44 and collars 45 by means of which the cock may be clamped to the wall of a kitchen sink. Nipples 43 are connected by a hollow member 46 at right angles thereto in which hotand cold water valves 47 and 48 aremounted. Between the valves 47 and 48 the connecting portion 46 has an enlarged central portion 49 within which there is formed an inner chamber 50 which extends from the front wall of the enlarged portion of the yfitting toward the rear wall thereof, there being a passage 51 extending around theread end of the chamber. The side walls of the chamber 50 extend from the top to the bottom of the enlarged portion 49 and this chamber is divided by partition 52 into front and rear portions, partition 52 having an opening 53 which is adapted to'be opened or closed by means of a valve 54, the stem 55 of which extends forwardly through a bushing 56 secured in the front wall of the chamber. Secured in a threaded opening in the wall of the chamber 50 there is a nozzle 57 which extends forwardly to adjacent the partition 52 and serves to normally direct the flow of water from the passage 51 through the opening 53 into the forward portion of the chamber 50. A narrow opening 58 is provided between the forward end of the nozzle 57 and the edge of the opening 53 by which communication is established between the passageway through the nozzle 57 and opening 53 to a space 59 surrounding the nozzle 57. In the bottom of the forward portion of the chamber 50 forwardly of the partition 52 there is an opening 60 through which the water may flow into a swinging discharge spout 61. Extending upwardly from the lit- 'v ting there is a nipple 62 to which a hose may be connected and this nipple communicates with the space 59 surrounding the nozzle 57. Vhen the valve 54 is open the water is shot through the opening 53 by the nozzle 57 and flows out through the opening 60 and spout 61, the discharge passageway through the spout being suiiciently unobstructed to permit the water discharged from the nozzle 57 to flow through the spout without creating When the valve 54 is closed, the water is forced as it issues from the nozzle 57 into the space 59 surrounding the nozzle 57 and through the upwardly extending nipple 62. In Figs. 13 and 14 of the drawing the invention is shown applied toacombined hot and cold water cock adapted to be attached to a `wash bowl. The construction ofthe body and fitting is almost identical with that 'shown in Figs. 9 to 12 and the same parts are, therefore, designated by the same reference numerals.l The only difference in the construction of the lixture is that the end nipples 63 extend downwardly from the connector for attachment to afhorizontally disposed spout, such asprovidedfor wash bowl cocks. `The upwardly extending nipple 62 in the kitchen sink and wash bowl cocks may have a hose attached thereto with a spray nozzle at its outer end, such spray nozzles' being commonly used in connection with kitcheny sinks for spraying dishes and in connection with wash bowls in barber shops for shampooing. v
